The 300 jounin star "quest"

Do we know exactly what happens when we collect 300 of these? I know it allows us to skip the JQ (Not sure exactly what room it puts you into), but is it

a one-time skip (Like taking a train to NLC)

or do you get an ETC item pass (Like florina beach)

or does he just remember you forever (Like the Kimera passageway in masteria)
